BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates generally to in line roller skates in particularto an inline roller skate including the arrangement of elements toprovide a shock absorbent independent wheel suspension mechanism toenable the inline roller skate to be used on irregular riding surfacesand for acrobatic type of riding mode including but not limited tojumping and the like by in line roller skate passenger.

2. Background

A common in line roller skate comprises a frame or chassis, having a topplatform with the sole of a boot secured to it for the foot of in lineroller skate rider. Side plates are rigidly secured to the underside oftop platform in vertical fashion opposing each other straddling skatewheels mounted about axles protruding side plates and securely attachedby appropriate fastening elements in a non relatable fashion. Axles areappropriately spaced between each other to enable unrestricted rotationof wheels during use of in line roller skate. The number of axles havingwheels attached along entire length of skate can vary and commonly isdependent upon size of wheel outer diameter but usually accounts to 2 ormore wheels. The wheels are usually arranged in a serial type inlinefashion specifically meaning that wheels are lined up along a commonlongitudinal center axis. The skates of the type as aforesaid are wellknown in the field of in line roller skates and exist in manyconfigurations and sizes. The type of suspension for wheels does notinclude an elastic element for shock absorbency to cushion leg of skaterider during skating action especially when running against an obstacleor other irregular surface feature. A great number of skate riders aremotivated to perform long jumping with the assist of ramps, curbs orother like features which requires a great deal of physical effort bythe skate rider to get airborne per se and consequentially requiringappropriate leg action for a cushioned landing to prevent injury to thebracing feet and legs. The like suspension of wheels on these inlineroller skates henceforth requires a considerable skill of the skaterider to perform acrobatics type of skate riding and then at best withinmarginal results.

3. Description of Related Art

The following art describes the present state of this field: U.S. Pat.No. 277,911 to Lutz describes a roller skate with a spring arm having asingle coil made of wire with permanent attachment to a footboard withsaid swing arm supporting at the distal end a wheel axle with a wheeltruck. During skating the weight of skater applied to said foot board incombination with skating action the like of pushing said roller skateagainst the ground will cause said spring arm to be deflected describingan articulated movement of said wheel truck and upon recoil of saidspring arm assist the skater towards improved acceleration in forwardmotion. Said spring arm may also afford a cushioned rebound beingtransferred to the foot of skate rider during the skating actionespecially when running against an obstacle or other irregular surfacefeature. Plurality of said spring arm is made of wire and independentlyfrom any other means supports front and rear wheel truck in itsentirety. Aforesaid in combination with the configuration of spring armmay not provide a preferred ride stability for the skater whendescribing lateral foot movements such as maneuvering around objects andobstacles specifically when negotiating change in directions such ascornering and the like. Further more the articulated spring action isconsiderably limited in range due to the fact that most of the springdeflection is being accomplished by said spring arm therefore requiringa greatly progressive spring force during deflection with provisions forrelatively small clearance between outer extremity of said skate wheeland underside of said foot board of said roller-skate. Aforesaidprogressive spring force means that the degree of spring deflection ofsaid spring arm from the start point of deflection to the end point orfullest extend of possible deflection requires a progressively largerforce applied by skater in proportion to the degree of springdeflection. In retrospect this feature may limit the ability of skaterto perform controlled jumping over obstacles and the like in additionmay also limit shock absorbency and rebound during skating specificallywhen the roller skate rider is negotiating irregularities on ridingsurface such as bumps, obstacles and other like objects.

U.S. Pat. No. 5,931,480 describes a foot gear suspension device withmovable swing arm with a nonrotating axis mounted to distal ends of saidswing arm having free rotating skate wheels. Opposite end of said swingarm is pivotally attached to frame work of said foot gear having asecondary pivot pin in line with said pivotal attachment connecting to alinear elastic element such as an air, hydraulic, or spring cushionedpiston or the like. The length of distance between said pivot pinsdetermines the degree of leverage and such articulated movement in thevertical plane of said swing arm. Said swing arm having a skate wheel isattached at either end of said foot gear frame work in such a mannerthat plurality of said skate wheel is in line with each other along thelongitudinal center axis of said foot gear. During skating the weight ofskater applied to said foot board in combination with skating action thelike of pushing the skate against the riding surface effects said swingarm to deflect down warily in an articulated movement and upon recoil ofelastic element assist the skater towards enhanced acceleration inforward motion. Arrangement of said swing arm may afford a shockabsorbency to leg of skater during skating activity especially whenrunning against protrusions in surface or during maneuvering aroundother like obstacles. The type of fixation of said swing arm providessufficient clearance to said framework of said footgear duringarticulated movement of said swing arm. Hence forth it appears thisinvention teaches optimization of movement in vertical plane of saidswing arm having said skate wheel therefore providing sufficientcapability for skater to perform jumping, negotiating obstacles and thelike. Said invention among others does not teach how the elasticity ofsaid swing arm is translating a proportional equal or nearly equal forceof rebound through out the complete range of pivotal and articulatedtravel of said swing arm. Specifically this invention does not explainsufficiently the relationship of the type of elastic element the like ofair, hydraulic, spring and other referenced herein and how theseelements are connected to and interfacing with said primary and saidsecondary pivotal arrangement of said swing arm. The present arrangementas shown and as specified in this invention may not make provisions foroptimized utilization of vertical movement of said swing arm and maydistribute a disproportional force of rebound in relation to theposition of said swing arm and along total travel range thereof. Inretrospect the skating may be very limited resulting in diminishedeffectiveness for jumping, acrobatics, negotiation of obstacles, surfaceirregularities and the like. Aforesaid is manifested by a progressivechange in elasticity or rebound force therefore requiring for the riderto compensate with proper leg action, balancing and physical strength.Therefore it may be highly likely that a diminished rebound force isassisting the rider wherein greater force may be required and inretrospect a greater force may be delivered when a smaller force forrebound may be sufficient. Limitations in the ability of skate rider touse rebound assist for acceleration in forward motion and performingjumping, acrobatics or negotiating riding surface obstacles or the likemay greatly increase the need of riders skill level and physicalstrength and may render a marginal ride stability at best. Saidinvention also fails to teach proper fixation of said swing armarrangement along the horizontal center axis of said pivot arrangement.Because of distal length from said pivot arrangement to said wheel ofsaid swing arm lateral forces or thrust applied to said swing arm byrider are of considerable force requiring a positive fixation to saidswing arm along longitudinal center axis of wheel and frame work thelike of wear plates straddling said swing arm rather depending on saidswing arm pivotal arrangement. Aforesaid may contribute to a greatlydiminished ride stability which more so with inline skates is ofsignificant importance to the riders safety when negotiating sharpturns, steeply banked corner riding, quick stops and the like. It is ofgreat attraction to an inline skateboard rider and of great incentive toacquire the skills of in line skating and once acquired to performacrobatic type riding. Therefore an in line skate board rider applies ona very frequent basis significant thrust onto said foot gear suspensionrequiring a considerably contained skating wheel suspension deliveringsuperior friction or grasp of skating wheel upon the riding surface. Thelike arrangement of said swing arm of this invention in combination withthe distal length between wheel axle and pivot point of said swing armexcluding a means of proper containment of said swing arm along thehorizontal axis the like of wear plate and other fixation elements maynot contribute to a desired ride stability for the skater and may limitsignificantly ride flexibility and safety. For further considerationthis invention fails to teach inclusion of more than 2 skating wheelsper said footgear. It is well known that ride stability and ride comfortand versatility is greatly enhanced with an in line skate having morethan 2 skating wheels.

My prior art search with abstracts described above teaches: several footgear suspensions including a design, but fail to teach an in line skatewith a fixated and unrestricted and shock absorbent skating wheelsuspension describing an articulated movement to be of constantdeflection force through the complete range of articulated movementwithout restrictive features to limit articulated movement. The presentinvention fulfills these needs and provides further related advantagesas described in the following summary.

Plurality of side bracket 15 is straddlingplurality of extension arm 12A and 12B respectively with plurality ofwear spacer ring 28 placed about plurality of axle 16 in rotatingfashion with plurality of wear spacer ring 23 placed about plurality ofaxle 16. Plurality of wear spacer ring 28 is abutting face of pluralityof side bracket 15 with opposite side of spacer ring 28 abutting face ofplurality of spacer 46 referred to on FIG. 3. Plurality of wear spacerring 23 is abutting face of plurality of hub of extension arm 12A and12B respectively. It is note worthy to mention that aforesaid isdemonstrating the effectiveness of said arrangement highlighting theconfinement for plurality of extension arm 12A and 12B respectivelyalong horizontal center axis in a pivotal fashion. Additionally it iseasily recognizable that precise alignment for plurality of skatingwheel 24 along the longitudinal center axis thereof is permanent andcannot not be misaligned during use if this invention.

FIG. 3 shows an embodiment of this invention in cross sectional view.Special designed skating boot 48—not shown—is firmly affixed to bootsupport plate 32. Platform 30 in horizontal plane is having plurality ofside bracket 15 affixed with plurality of counter sink screw 17—notshown—along underside thereof in perpendicular plane. Extension arm 12Aand 12B respectively is pivotally and coaxially affixed about pluralityof axle 16 and rotated in angular position—partially shown—to a forklike position with distal end of extension arm 12A of mirror image toextension arm 12B. Extension arm 12A and 12B respectively is having askating wheel affixed to axle 21 thereof affixed in non rotating fashionto distal end of extension arm 12A and 12B respectively with lock washer44 and nut 34 threaded onto end thereof. Skating wheel 24 is pivotallyaffixed about axle 21 with lock washer 44 and nut 34 threaded ontoopposite end of axle 21. Axle 16 is protruding through hole forplurality of side bracket 15 at one end and opposite end thereof withlock washer 44 and nut 34 rendering axle 16 affixed in a non rotatingfashion. Plurality of side bracket 15 is straddling extension arm 12Aand 12B respectively with plurality of wear spacer ring 28 placed aboutaxle 16 abutting face of plurality of side bracket 15 with opposite sidethereof abutting face of plurality of spacer 46. Wear spacer ring 23 isabutting face of hub for extension arm 12A and 12B respectively.Aforesaid is demonstrating the effectiveness of said arrangementhighlighting the precise confinement of extension arm 12A and 12Brespectively along horizontal center axis and axle 16 respectively.Aforesaid is high lighted due to the fact that the overall length ofcenter portion of axle 16 is denominating a larger circumference thanend portions thereof and to be of minutely greater linear lengththerefore exceeding the sum of cross sectional length for plurality ofwear spacer 28 and wear spacer 23 and plurality of spacer 46 and ofextension arm 12A and 12B respectively. Therefore extension arm 12A and12B respectively is contained along the horizontal axis of axle 16 andcapable of rotational movement thereof during use of this invention.Specifically containment of extension arm 12A and 12B respectively issecured by the contiguous effect with face of plurality of wear spacer28 with plurality of contiguous face of side bracket 15 and the oppositeside with plurality of contiguous face of spacer 46 and respectively theopposite contiguous face of plurality of spacer 46 with the contiguousface of extension arm 12A and 12B respectively with opposite contiguousface thereof and contiguous face of wear spacer 23. Plurality of sleevebearing 25 is of free rotational fashion about axle 16 and is sweatfitted with extension arm 12A and 12B respectively rendering thereofconfined to a non rotational fixation about extension arm 12A and 12Brespectively.

It is noteworthy to mention theimportance of the precise confinement of extension arm 12A and 12Brespectively by simultaneously providing proper rotational bearingsupport thereof about axle 16. Plurality of torsion spring 14 isencircled by counter bore of extension arm 12A and 12B respectively andis aligned with plurality of spacer 46. Torsion spring 14 is of a wirematerial of a given hardness, elasticity, cross section as well ishaving a certain number of coils therefore providing a certain springforce to be adequate for the desired torque strength required and to betransmitted to plurality of wheel 24 via partial rotation of extensionarm 12 A and 12 B respectively. Plurality of torsion spring 14 has anextension 52 along the horizontal plane on one end of coil thereof withthe like at the opposite end of coil thereof respectively. Plurality ofextension 52 inserts into plurality of through hole 50 and plurality ofthrough hole 62 respectively therefore confining extension arm 12A and12B respectively to a given position or home position along the verticalplane depending on location of through hole 62. It is contemplated thatthrough hole 50 is of elongated configuration along the vertical centeraxis thereof. Aforesaid is anticipated to compensate for diametricalchange of torsion spring 14 during deflection thereof. For an alternatemethod to compensate for diametrical change of torsion spring 14 anelongated hole 50 may be substituted with a dog point urging against endportion of coil for torsion spring 14—not shown. It is noteworthy tomention that the rotational movement or articulation of extension arm12A is in the opposite direction to extension arm 12B when torqued ordeflected during use of this invention by an in line skate board rider.Torsion spring 14 paired with extension 12A is installed in mirror imageto torsion spring 14 paired with extension 12B which readily isaccomplished by rotating thereof half circle in horizontal plane priorto installation.
